摘要
HJ-1-C卫星是我国环境与灾害监测预报小卫星星座的一颗合成孔径雷达卫星,与光学卫星HJ-1-A/B共同完成环境与自然灾害监测。该文介绍了中国第1颗民用SAR卫星的系统总体及载荷的设计特点,研究了卫星平台部分的数传、姿态控制、供配电和热控分系统对SAR载荷的支持能力以及相互之间的匹配关系,同时,给出了卫星在轨测试验证的相应结果。
HJ-1-C is a SAR satellite owned by the Chinese Environment and Natural Disaster Monitoring constellation, and works together with the optical satellites HJ-1-A/B for monitoring environment and natural disasters. In this paper, the system design and characteristics of the first Chinese civil SAR satellite are described. In addition, the interface relation between SAR payload and platform is studied. Meanwhile, the data transmission capability, attitude, power, and temperature control that support SAR imaging are reviewed. Finally, the corresponding in-orbit verification results are presented.
